Flexible waterproof casing is a pipe fitting mainly used for building waterproofing, its common anti-corrosion treatment techniques include the following:

2 . Lining treatment technology: this technology can form a layer of anti-corrosion layer inside the flexible waterproof casing, so as to enhance its waterproof performance, commonly used methods include polyethylene lining, fluorine plastic lining, etc.
3 . UV exposure treatment technology: this technology can be in the field environment of flexible waterproof casing UV exposure, thereby enhancing its anti-corrosion performance, but need to be carried out in a specific environment, not applicable to indoor.
